您要查找的是不是:
- mean minimum flow 平均枯水流量
- The mean minimum temperature of 21.2 degrees ranked highest for November. 平均最低气温为21.;2度,也是十一月份的最高纪录。
- The minimum flow requirements must be maintained between 8 and 9 gpm. 最小流量要求必须维持在8和9美制加仑/分钟。
- Using the minimum flow capability, begin at step 1 to the size you will need for this low-flow by-pass. 采用这个最小流量能力,从步骤1开始选择用户需要的用于低流量旁路的通径。
- Criteria for selection is minimum flow, normal flow, maximum flow and pressure drop across the valve. 选型标准是最小流量,正常流量,最大流量和通过阀门的压降。
- The net result is little change in the daily maximum temperature. Overall, the annual mean temperature rises but at a slower rate than the annual mean minimum temperature. 综合最高和最低气温的变化,日平均温度有上升的趋势,但速度较日最低气温慢。
- The minimum flow rate through a tray (turndown) is higher than most trays before the tray experiences weeping. 讲的是筛板塔的缺点,意思是为防止漏液,筛板塔所需要的最小流量比其他类型的塔板要高。
- Step 6: From this point draw a vertical line down to the horizontal axis. This will be the minimum flow capabilitiesof the valve based on these variables. 步骤6:从这一点划垂线向下与横轴相交。这就是以这些变量为基础的阀门的最小流量能力。
- A software minimum flow stop provision is included to maintain a minimum flow/pressure to the nozzles.This would typically be active during turndown operation. 包括一个??设施,以维持到喷嘴的最小流量/压力。它一般会在降负荷操作期间起作用。
- In the end, Victoria and New South Wales agreed to ensure a minimum flow to South Australia and to divide the remaining water equally between themselves. 最后,维多利亚和新南威尔士两州同意保证南澳大利亚州一个最低流量,然后将剩下的河水流量平分。
- The estimations of the minimum flows are 1 .46cms in the flooding season and 0 .61 cms in the dry season. 推估值于丰水期之基础流量应为 1.;4 6 cm s;枯水期应为 0
- Mean minimum temperature during flowering to autumn stage 开花到成熟期平均最低温度
- minimum flow recirculation system 最小流量再循环系统
- Seat bores and minimum flows are crucial in check valve selection. Without proper sizing, extreme damage can occur in check valve internals. Pulsed flow reversals can also cause damage. 阀座孔和最小流量对于止回阀的选型至关重要。没有适当的通径,可能会造成止回阀内部严重损坏。脉冲式倒流也可能导致损坏。
- minimum flow quantity of motor vehicle 机动车保有量
- Do you mean say we are met for a thunder storm? 你肯定我们会遇到一场雷雨?
- I feel mean for not doing more for my son. 我对没为我儿子多做点事而感到惭愧。
- Defeat in this election would mean he was done for. 这场选举的失败意味着他政治生涯的结束。
- By power we mean the rate of doing work. 我们说功率就是指做功的速率。
- We have pared down our expenses to a bare minimum. 我们已最大限度地削减了开支。
